San Luis Obispo Creek is an important steelhead stream in central California. Over the years, this coastal stream had been impacted by urban development and pollution. The City of San Luis Obispo decided to extend the downtown creek trail and restore the stream. The channel was in an extremely degraded condition and erosion was actively occurring. Much of the riparian vegetation had been lost due to erosion and encroachment of urban land uses. Don Funk designed the channel restoration improvements and assisted the engineering firm, Cannon, and the landscape architectural firm, FIRMA, with the grading design and re-vegetation plans. After conducting a morphological survey of the channel, we prepared improvement drawings for boulder structures, including multiple rock weirs and rock veins to curb future erosion, improve water quality and restore stream habitat. The plan also included lowering the north terrace and reducing the slope of some of the channel banks to improve bank stability and slow creek velocities adjacent to the banks, helping to reduce channel erosion. Native riparian vegetation was incorporated in the restoration along the channel banks. Don Funk also provided on-site construction management during the channel grading and creek restoration work.
